feat(desktop): Tauri auto-updater wired to GitHub Releases#62
Merged
Conversation
When DeepCode.app launches: 1. Background poll of https://github.com/oratis/deepcode/releases/latest/download/latest.json 2. If a newer version exists → download in background, signature-verify with ed25519 pubkey 3. Fire `update-downloaded` event → renderer shows UpdateBanner 4. User clicks "Relaunch now" → tauri-plugin-process relaunch() → new version starts · apps/desktop/src/lib/updater.ts (NEW) — startUpdaterPolling / onUpdateDownloaded / relaunchNow. Silent on offline / 404 (early ship phase has no releases yet). · apps/desktop/src/App.tsx — calls startUpdaterPolling on mount, subscribes both shim + real updater. · apps/desktop/src/components/UpdateBanner.tsx — "Relaunch now" now actually calls relaunchNow(). Shows "Relaunching…" state. · apps/desktop/src-tauri/tauri.conf.json — updater.active=true, endpoint, pubkey (ed25519 generated via `tauri signer generate`). Private key at ~/.tauri/deepcode-updater.key (gitignored — must be backed up by maintainer). · apps/desktop/src-tauri/Cargo.toml — added tauri-plugin-process. · apps/desktop/src-tauri/src/lib.rs — registers plugin-process. · apps/desktop/src-tauri/capabilities/default.json — added process permissions. · apps/desktop/package.json — added @tauri-apps/plugin-process. When the maintainer cuts a release (git tag v0.X.Y), they need to: 1. Run sign-and-notarize.sh — produces signed .app + .dmg 2. Sign update artifacts with the private key via `tauri signer sign` 3. Generate latest.json pointing to the signed .tar.gz/.zip 4. Upload to GitHub Releases v0.X.Y The auto-update flow then kicks in for every installed client.

On launch: silent poll → if newer release exists, background download + ed25519 verify → UpdateBanner. Relaunch button calls tauri-plugin-process.relaunch(). Pubkey embedded in tauri.conf.json (private key at ~/.tauri/deepcode-updater.key — must be backed up). Closes M9 auto-update item.
